The controller may display a plurality of characters on the user interface of the display prior to acquiring the first trajectory. The plurality of characters may be written directly on the user interface by a user through a sliding instruction. Alternatively, the plurality of characters may be entered into the controller by the user via a keyboard.

Under the condition that a plurality of characters are displayed on a user interface, a user can draw a first track surrounding the plurality of characters on the user interface through a first user touch instruction, and when the controller detects the first user touch instruction acting on the plurality of first characters, the track of the first user touch instruction can be obtained, and the track of the first user touch instruction is the first track.

Step 402, drawing an outer frame surrounding a plurality of characters based on the first track.

Because the first track is triggered and generated by the user through the first user touch instruction, and the first track is generally an irregular graph similar to a rectangle, in the embodiment of the application, the controller can correct the first track when drawing the outer frame based on the first track, so as to obtain the outer frame of the regular graph.

For example, assuming that the first track is a curve surrounding a plurality of characters, an outer frame obtained by correcting the curve by the controller may be a rectangle surrounding the plurality of characters.

Of course, the shape of the frame drawn by the controller based on the first track may be the same as the first track, that is, the controller may directly use the first track as the frame. For example, when a user draws a first track surrounding a plurality of characters in a user interface, the first track may be a regular rectangle, and the controller may directly take the first track as an outline frame.

In step 403, a second track for separating the plurality of characters is acquired in the area surrounded by the outer frame based on a second user touch instruction input on the user interface.

After the controller draws the outer frame on the user interface, the user can draw a second track for separating a plurality of characters on the user interface through a second user touch instruction in the area surrounded by the outer frame. When the controller detects a second user touch instruction acting on the user interface, the controller can acquire the track of the second user touch instruction, and the track of the second user touch instruction is the second track.

Step 404, drawing an inner scribe line for separating the plurality of characters in the outer frame based on the second trajectory.

Because the second track is generated by triggering a user through a touch instruction of the second user, and the second track is usually an irregular line, in the embodiment of the application, the controller can correct the second track to obtain the inner scribing line of the regular line when drawing the inner scribing line based on the second track.

For example, assuming that the second trajectory is a curve separating a plurality of characters, an inner scribe line obtained by correcting the curve by the controller may be a straight line separating a plurality of characters.

Of course, the shape of the inner scribe line drawn by the controller based on the second track may be the same as the second track, that is, the controller may directly use the second track as the inner scribe line.

Step 405, generating a table according to the outer frame, the inner score and the plurality of characters.

In the embodiment of the application, the controller can determine a plurality of grids formed by the outer frame and the inner scribing as a plurality of cells of the table, and determine characters displayed in the area where each cell is located as content data of the cell, so that the table is obtained. The controller may edit, select, copy, save, etc. the form in response to a user-triggered operation instruction. Wherein the editing of the table by the user is usually performed in units of cells. Optionally, the user edits the cells, including moving characters into and out of the cells.

In summary, the embodiments of the present application provide a table generating method, which may draw an outline on a user interface based on a first track surrounding a plurality of characters, and then draw an inner line on the user interface based on a second track separating the plurality of characters. Finally, a form is generated based on the outline, the inner score, and the plurality of characters. According to the table generation method provided by the embodiment of the application, under the condition that a plurality of characters are displayed on the user interface, a user can draw tracks for separating the plurality of characters on the user interface according to the arrangement condition of the plurality of characters, and the controller draws an outer frame and an inner scribing line according to the obtained tracks and can automatically generate the table based on the outer frame, the inner scribing line and the plurality of characters. In the process of generating the table, a user does not need to adjust the table in the process of inputting characters, and the table generation method is simple to operate and high in flexibility.

Fig. 6 is a flowchart of another table generating method according to an embodiment of the present application. The method may be applied to the controller 210 of the display device 200 shown in fig. 1. As can be seen with reference to fig. 6, the method may include:

step 501, acquiring a first track surrounding a plurality of characters based on a first user touch instruction input on a user interface.

The plurality of characters 601 may be displayed on the user interface 60 before the controller obtains the first trajectory of the plurality of characters. Each character may be: numbers, letters or chinese characters, etc. Wherein the plurality of characters 601 may be written by a user on the user interface 60 via a sliding instruction. Alternatively, the plurality of characters 601 may be input to the controller by a user through a keyboard.

As shown in fig. 7 and 8, assume that a plurality of characters 601 are displayed on the user interface 60: the first part, the second part, description 1, description 2, responsible person 1, responsible person 2, and the user may draw a first track 602 surrounding the plurality of characters 601 on the user interface 60 via a first user touch instruction. When the controller detects a first user touch instruction acting on the user interface 60, the controller may acquire the track 602 of the first user touch instruction, where the track 602 of the first user touch instruction is the first track.

The first user touch instruction may be an instruction that a user slides on the user interface through a finger. Alternatively, the first user touch instruction may be an instruction that the user slides on the user interface through the electronic pen. Alternatively, the first user touch instruction may be an instruction that the user slides on the user interface through a mouse.

Step 502, if the first track is detected as a rectangle, drawing an outer frame of the rectangle for surrounding the plurality of characters.

In the embodiment of the present application, since the first track is generated by triggering the user through the first user touch instruction, the first track is usually an irregular pattern. Therefore, in the embodiment of the present application, when the controller draws the outer frame based on the first track, the controller may first identify the first track to determine whether the first track is rectangular. When the first track is identified, the area of the area surrounded by the first track can be determined first, if the ratio of the area surrounded by the first track to the area of the smallest circumscribed rectangle of the first track is greater than the ratio threshold, the first track can be determined to be rectangular, and the rectangle can be irregular, namely, the first track is an irregular pattern similar to the rectangle.

Referring to fig. 9, when the controller determines that the first track is an irregular rectangle, the first track 602 may be corrected to obtain a regular rectangular outer frame 603 with each side being a straight line. For example, the outer frame 603 may be a minimum bounding rectangle of the first trace 602.

It should be noted that, if it is detected that the first track is not rectangular, the controller may directly display the first track on the table display interface.

In step 503, a second track for separating the plurality of characters is acquired in the area surrounded by the outer frame based on a second user control instruction input on the user interface.

After the controller draws the outline 603 on the user interface 60, the user may draw a second track for separating a plurality of characters on the user interface 60 through a second user touch instruction within the area surrounded by the outline. When the controller detects a second user touch instruction acting on the user interface, the controller can acquire the track of the second user touch instruction, and the track of the second user touch instruction is the second track.

The second user touch instruction may be an instruction that the user slides on the user interface through his own finger. Alternatively, the second user touch instruction may be an instruction that the user slides on the user interface through the electronic pen. Alternatively, the second user touch instruction may be an instruction that the user slides on the user interface through the mouse.

For example, assuming that a second track drawn by the user through the second user touch instruction at the user interface 60 is a line 604a shown in fig. 10, the second track 604a acquired by the controller may divide the plurality of characters 601 into two groups, where the first group of characters includes: "first part", "description 1", and "responsible person 1", the second set of characters includes: "second part", "description 2", and "responsible person 2".

Step 504, detecting whether the second track meets the drawing condition.

In an embodiment of the present application, the drawing conditions may include: the area of the overlapping area of the second track and the plurality of characters is smaller than an area threshold value, and the distances between the starting point and the ending point of the second track and the side line of the outer frame are smaller than a distance threshold value. Alternatively, the distance threshold may range from 5 pixels to 35 pixels.

It should be noted that, assuming that the plurality of characters are written on the user interface by the sliding instruction, the strokes of a certain character of the plurality of characters may be longer due to the writing habit of the user, and thus the second track drawn by the second user touch instruction may overlap with the strokes of the certain character. Therefore, in the embodiment of the present application, the controller may be preconfigured with an area threshold. By setting the area threshold value to judge whether the second trajectory satisfies the drawing condition, the reliability of judgment can be improved.

For example, assuming that the distances between the start point and the end point of the second trajectory and the boundary of the outer frame are both smaller than the distance threshold, when the area of the overlapping region of the second trajectory with the plurality of characters is smaller than the area threshold, the controller may determine that the second trajectory overlaps at least one character of the plurality of characters due to writing habits of a user, the second trajectory satisfying the drawing condition.

Assuming that the distances between the start point and the end point of the second track and the boundary of the outer frame are smaller than the distance threshold, when the area of the overlapping area of the second track and the plurality of characters is equal to or larger than the area threshold, the controller may determine that the area of the overlapping area of the second track and the plurality of characters is larger, possibly resulting in misoperation of a user, and the second track does not meet the drawing condition.

When the controller detects that the second trajectory satisfies the drawing condition, step 505 may be performed; when the controller detects that the second trajectory does not satisfy the drawing condition, step 506 may be performed.

Step 505, drawing an inner scribe line for separating the plurality of characters in the outer frame based on the second trajectory.

Because the second track is triggered and generated by the user through the touch instruction of the second user, and the second track is usually an irregular line, in the embodiment of the application, when the controller detects that the second track meets the drawing condition and draws the internal scribing based on the second track, the controller can correct the second track to obtain the regular internal scribing.

For example, referring to fig. 10, the second trace 604a does not have an overlapping region with the plurality of characters 601. The first distance between the start point of the second track 604a and the upper edge of the outer frame 603 is smaller, and the second distance between the end point of the second track 604a and the lower edge of the outer frame 603 is smaller, and both the first distance and the second distance are smaller than the distance threshold. Since the second trajectory 604a satisfies the drawing condition, the controller may correct the second trajectory 604a to draw the inner scribe line 605a within the outer frame 603. Referring to fig. 11, the inner score line 605a may be a straight line parallel to the left and right lines of the outer frame 603.

In an embodiment of the present application, referring to fig. 12, the second track 604b drawn on the user interface 60 by the user through the second user touch command may also be a curved line. If the controller detects that the bent curve meets the drawing conditions, the controller can correct the bent curve to obtain the inner scribing line of the regular line. For example, the resulting internal score line may be a broken line or a straight line.

For example, as shown in fig. 12, it is assumed that the second trace obtained by the controller is a curved line 604b, and the second trace 604b may divide a plurality of characters into two groups, where the first group of characters includes: "first portion", "second portion", and "description 2". The second set of characters includes: "description 1", "responsible person 1", and "responsible person 2". From the above-described drawing conditions, it can be determined that the second trajectory 604b shown in fig. 12 also satisfies the drawing conditions, and the controller can draw the inside-line 605b in the outer frame 603 based on the second trajectory 604 b. For example, referring to fig. 13, the inner score 605b may be a fold line. Alternatively, referring to fig. 14, the controller may adjust the positions of the plurality of characters in the user interface and draw an inner scribe line 605b based on the second trajectory 604b, and the inner scribe line 605b may be a straight line. Referring to fig. 14, the inner score 605b may divide a plurality of characters into left and right parts, and the inner score 605b may be parallel to left and right lines of the outer frame. Of course, the inner score 605b may also divide the plurality of characters into upper and lower parts, and the inner score 605b may be parallel to the upper and lower edges of the outer frame. The embodiment of the present application is not limited thereto.

In this embodiment of the present application, the drawing conditions may further include: the starting point and the ending point of the second track are both positioned in the outer frame, the distance between the starting point of the second track and the first side line of the outer frame is smaller than a distance threshold, and the distance between the ending point of the second track and the second side line of the outer frame is smaller than the distance threshold. The first side line and the second side line may be two opposite sides of the outer frame. That is, the second track is located in the outer frame.

Further, the drawing conditions may further include: the difference between the length of the connecting line between the starting point and the ending point of the second track and the actual length of the second track is smaller than a difference threshold, and the distance between the starting point and the ending point of the second track in the target direction is smaller than a distance threshold. Wherein the target direction is perpendicular to the first and second edges of the outer frame. That is, the second track should be substantially parallel to both the first and second edges of the outer frame.

Alternatively, the spacing threshold may be 50 pixels and the gap threshold may be 50 pixels.

In the embodiment of the present application, assuming that the row direction of the pixels in the controller is the horizontal axis (X-axis) and the column direction of the pixels is the vertical axis (Y-axis), the first side line and the second side line of the rectangular frame drawn by the controller may be parallel to the X-axis, i.e., the first side line and the second side line may be the upper side line and the lower side line of the frame, respectively. Alternatively, the first and second edges may be both parallel to the Y-axis, i.e., the first and second edges may be left and right edges of the outer frame, respectively.

For example, the second track 604a shown in fig. 10 does not have an overlapping area with the plurality of characters, the start point and the end point of the second track 604a are both located in the outer frame, the distance between the start point of the second track 604a and the upper edge line of the outer frame is smaller, the distance between the start point of the second track 604a and the lower edge line of the outer frame is smaller, and the second track 604a is substantially parallel to the upper edge line and the lower edge line of the outer frame, so that the second track 604a shown in fig. 10 satisfies the drawing condition.

Although the second track 604b shown in fig. 12 does not have an overlapping area with the plurality of characters, the start point and the end point of the second track 604b are both located in the outer frame, and the distance between the start point of the second track 604b and the left line of the outer frame is smaller, and the distance between the start point of the second track 604b and the right line of the outer frame is smaller, but the second track 604b is not parallel to each line in the outer frame 603, so that the second track 604b shown in fig. 12 does not satisfy the drawing condition.

In an embodiment of the present application, referring to fig. 11, after the controller draws an inner scribe line 605a on the user interface 60 based on the second track, referring to fig. 15, if the user executes the second user touch instruction again in the user interface 60 shown in fig. 11, the controller may acquire the track 604c of the second user touch instruction. As shown in fig. 16, the controller may draw an inner scribe line 605c based on the trajectory 604c of the second user touch command. Still further, referring to fig. 17, if the user executes the second user touch command again in the user interface 60 shown in fig. 16, the controller may acquire the track 604d of the second user touch command. And, as shown in fig. 18, the controller may draw an inner scribe line 605d based on the trajectory 604d of the second user touch command.

Step 506, displaying the second track.

When the controller detects that the second track does not meet the drawing condition, the controller may display the second track. When the area of the overlapping area of the second track drawn by the user through the second user touch instruction and the plurality of characters is greater than or equal to the area threshold, the controller can determine that the second track is generated by misoperation of the user, so that after the controller displays the second track, prompt information can be displayed, and the prompt information is used for prompting the user whether to delete the second track.

Step 507, when a form generation instruction is detected, a plurality of grids formed by the outer frame and the inner scribe line are determined as a plurality of cells of the form.

In the embodiment of the application, the form generation instruction may refer to a user touch instruction acting on the outside of the outer frame, or may refer to a click instruction of a generate form button acting in a user interface. When the controller detects that the table generation instruction generates the table, the grids formed by the outer frame and the inner scribing line can be determined as the cells of the table.

By way of example, referring to fig. 11, assuming that one inner scribe line is drawn in the outer frame, the outer frame and the inner scribe line may constitute two grids that may serve as two cells of a table, i.e., the table may be a 1 row and 2 column table.

Alternatively, referring to fig. 16, assuming that two inner scribe lines are drawn in the outer frame, the outer frame and the inner scribe lines may constitute four grids that may be four cells of a table, that is, the table may be a 2-row and 2-column table.

Alternatively, referring to fig. 18, assuming that three inner scribe lines are drawn in the outer frame, the outer frame and the form scribe lines may constitute six grids that may serve as six cells of the form, that is, the form may be a 3-row 2-column form.

And 508, determining the characters displayed in the area where each cell is located as content data in the cells, and obtaining a table.

After determining a plurality of cells of the table, the controller may identify the characters displayed in the area where each cell is located, and fill and display the characters displayed in each cell in the cell, that is, may determine the characters displayed in the area where the cell is located as content data in the cell, so as to obtain the table.

For example, referring to fig. 18, the controller may determine the character "first portion" displayed in the area where the first row and first column cells are located as the content data within the first row and first column cells. And determining the second part of the character displayed in the area where the first row and the second column of cells are positioned as the content data in the first row and the second column of cells. And determining the character 'description 1' displayed in the area where the first column cell of the second row is positioned as the content data in the first column cell of the second row. And determining the character 'description 2' displayed in the area where the second row and second column cells are located as the content data in the second row and second column cells. And determining the character 'responsible person 1' displayed in the area where the third row and first column cells are located as the content data in the third row and first column cells. And determining the character 'responsible person 2' displayed in the area where the third row and second column cells are positioned as the content data in the third row and second column cells.

It should be noted that, a table generally includes multiple rows and/or columns, and after a change in the size of a cell in the table, the same row or column of cells may be affected. Therefore, when the controller generates the table, the height of each row of cells is set to be the same, and the width of each column of cells is set to be the same, so that the attractive coordination of the table is ensured.

Step 509, adjusting a display effect of at least one element of the plurality of characters, the outer frame and the inner scribe line.

In the embodiment of the application, before the controller detects the form generation instruction, the controller can display the outer frame, the inner scribing line and the plurality of characters on the user interface according to the preset display effect. When the controller detects the form generation instruction, the display effect of at least one element in the plurality of characters, the outer frame and the inner scribing line can be adjusted, so that a user can conveniently distinguish whether to generate the form. And, the controller can edit, select, copy or save the table in response to the operation instruction triggered by the user.

Alternatively, the display effect of the at least one element may include colors of the outer frame, the inner scribe line, and the plurality of characters, widths of the outer frame and the inner scribe line, and a font size of the plurality of characters, etc.

For example, the outline, the inner line, and the plurality of characters of the user interface display may all be green before the controller detects the form generation instruction. The controller may adjust colors of the outer frame, the inner scribe line, and the plurality of characters to black when detecting the form generation instruction.

Alternatively, referring to FIG. 19, the controller displays the outline and the line of the inside score at a width of 0.75 lbs. before detecting the form creation instruction. The controller may adjust the width of both the outer and inner score lines to 2 pounds when the form generation command is detected.
